Abstract

Introduction: Laparoscopic proctectomy preserving sphincter in rectal cancer is a topic that has attracted many study authors. This study was conducted to evaluate surgical and oncological outcomes in a group of patients with low rectal cancer with sphincter-preserving laparoscopic proctectomy. Materials and Methods: This is a prospective descriptive study on a group of patients with low rectal cancer according to Japanese criteria. This group of patients underwent sphincter-preserving laparoscopic rectal resection by the same technique performed by a single surgical team. Results: The total number of patients in the study was 35 patients including 68,6% men and 31% women, with a mean age of 65.07 ± 11.2 years. All 35 patients had tumors located below the peritoneal fold and mainly stage II (74.3%). The average operative time was 247.7 ± 46.5 minutes. The mean intraoperative blood loss was 28.3 ± 6.5 ml. Time for re-feeding after surgery is 5.3 ± 1.4 days. There were no complications during surgery. The total number of postoperative complications was 22.8%, but most of the complications were mild and there were no deaths. The mean postoperative time was 10.7 ± 2.8 days. The majority of patients discharged from the hospital gave good results 77.1%, there were no patients discharged with bad results. The results of postoperative follow-up showed that the group of patients had good results. Conclusion: Laparoscopic surgery for sphincter-preserving low rectal cancer of the above group of patients is safe, without intraoperation accident, and with few complications.
